Equations:
y = 20x
y = 20x + 10
y = 20x - 15
The second and third graphs are related to the first graph by having parallel slope, due to the increase in cost total is $20/month.

The normal quadratic equation would be y=ax^2+bx+c.
The variable c is the y intercept, so let's get y to itself.
y+4=(x+2)^2 (square this side.)
y+4=x^2+4x+4 (subtract the 4 on the y side to isolate the y.)
y=x^2+4x
The y intercept is zero.
Answer:
23.3786
Step-by-step explanation:
tan33° = x÷36
x = tan33°×36
x = 23.3786
